This invention relates to certain new and useful improvements in pinboards and more The main object of the invention is to pro- Vide a pinboard or frame which can be economically produced and is of strong,rigid and lasting construction adapted to effectively support bobbinsfor steaming or other processing.

A further object resides in the construction of frame which permits,when desired, of forming the parts thereof from aluminum to eliminateany chance of the yarn or thread being contaminated by rust.

Other objects and advantages relate to the details of the structure andthe form. and

the relation of the parts thereof, all as will i str psii at eachintersection are formed with more fully appear from the followingdescription, taken in connection with the accompanying drawing, in whichFigure 1 is a perspectiveview of a pm board of this invention.

Figure 1.

Figure 3 is a cross section on line 33, Figure 1.

Figure 4 is an enlarged'section through the lower portion of one of thepins and the overlying cross strips illustrating the manner of rigidlysecuring these parts together.

The pin board, as here illustrated, comprises a frame 1 which may beformed of frame. A secondary set of cross strips 5 are providedextending between the opposite ends 6 and 7 of the frame beneath theprimary wire bent into the desired form as, forin- 1931. Serial No.540,920.

strips 2 butin contact therewith at their inthese strips are secured toeach other and t0 a pin 8 in a new and novel manner to produce animproved construction.

For this purpose, the upper strips 2 at each intersection are formedwith an opening 9 which may as shown, be of cylindrical form and ofuniform diameter throughout. As'distinguished from this, the underlyingopenlngs 10 registering with the respective openings 9,, but theseopenings or holes 10 are reamed with a taper so as to provide asubstantially frusto-conical surface.

Each pin 8 is formed near its lower end with a. radial enlargement orshoulder 11 havinga fiat bottom surface adapted to rest snugly upon thestrip 2, and the portion of the pin below the shoulder 11 may, ifdesired, be slightly reduced in diameter as compared 7 with the diameterof the body of the pin and is of a size adapted to fit tightly in theopening 9 and extend into the t pered opening 10 in the strip 5. I

With this construction of parts, a rigid and permanent securement of thepin to the strips 38 2 and 5 is effected by riveting the lower end ofthepin 8 and enlarging it in this manner so as to fit tightly in thetapered opening 10, drawing the shoulder 11 tightly against the strip 2and rigidly securing the strips together at each intersection. Thisconstruction of connection or mounting of the pins rigidly secures thepins to both of the cross strips 2 and 5, and at the same time, securesthe two strips together at each intersection thereby n reinforcing andstrengthening the entire frame construction.

'The lower ends of the pins 8 after riveting, as perhaps best shown inFigure 4, may if necessary, be smoothed off in any suitable manner sothat their enlarged lower ends constitute an unbroken smoothcontinuation of the lower surface of the strips 5 so that the strips 5may constitute effective supports for the frame upon which it slidesreadily and easily.

I claim:

1. A pin board comprising a frame, primary and secondary sets of crossstrips secured to the frame and intersecting each other, said stripshavingregistering openings at their intersections, and the openings inthe. secondary strips having a tapered wall, and pins having shouldersresting upon: the primary strips and their lower portions extendingthrough said registering openings and their lower ends enlarged to fittightly within said I tapered wall to firmly unite the pin and the setsof cross strips together.

2; A pin board comprising a frame, a primary set of cross strips havingtheir ends bent upwardly around the frame, a set of secondary stripsunderneath the primary strips extending at substantially right angles tothe, primary strips and having their ends bent upwardly around theframe, said sets of strips having registering openings at theirintersections, the openings in the secondary strips having a downwardlyand outwardly inclined Wall, and pins having shoulders resting upontheprimary strips, and portions beneath the shoulders extending throughsaid registering openings and the lower ends of said pins being rivetedto the secondary strip and fitting tightly within said tapered walls. Inwitness whereof I have hereunto set my hand this 14th day of May, 1931.
